In recent years, artificial islands have been widely constructed in coastal areas to quickly obtain high-quality land resources. However, the construction of artificial islands may exert substantial effects on the distribution patterns and transport processes of offshore seabed sediments. To understand the changes and transport characteristics of sediments after the construction of artificial islands, this article focuses on the impact of Nanhaimingzhu (NHMZ) artificial island on the properties and distribution of offshore seabed sediments in the Haikou Bay. With surface sediments sampled respectively in the offshore of the Haikou Bay before and after the construction of NHMZ artificial island, the changes in sediment characteristics were analyzed. The impact of NHMZ artificial island on the surface sediments properties and transport trend in the Haikou Bay was discussed with sedimentary dynamic and grain size trends analysis. The results showed that the surface sediment properties changed significantly after the construction of NHMZ artificial island, with the fine-grained sediment composition increased, grain size decreased and the sorting worsen. It was found that the weakening of sedimentary dynamic conditions in the Haikou Bay caused by NHMZ artificial island was an important factor for the changes in seabed surface sediments grain size and the trend of sediment transport.
